hwmon: (it87) Don't arbitrarily enable temperature channels
Temperature channels can be used in 2 different modes (thermistor and thermal diode) and we don't know which one, if any, is correct for every given board. So don't arbitrarily choose one. Instead, leave the temperature channels untouched. They can be configured from user-space if needed anyway. Signed-off-by: Jean Delvare <khali@linux-fr.org>
